Dorkin's first contribution to the line was as artist and co-creator on the second Predator series, the much-acclaimed Predator: Big Game in 1991, the first series to move the story beyond the movie mythos with the introduction of its hero, Native-American Corporal Enoch Nachai.

His second contribution was as writer on the equally gory and hard-hitting Predator: Bad Bloodin 1993-4, which introduced the idea of rogue, homicidal Predators called Bad Bloods.
